Google lists 2,305 LeetCode interview questions while Turing lists 37. They share 33 problems — 1% of Google's bank and 89% of Turing's. Focus on the overlap first, then drill into 2,272 Google-only and 4 Turing-only questions.
Overview
Preparation Strategy
Step 1 — Shared core: Solve the 33 overlapping problems first. These are the highest-yield questions for candidates interviewing at both Google and Turing.
Step 2 — Company-specific depth: Add Google-specific problems like Add Two Numbers, Trapping Rain Water, Palindrome Number and Turing-specific problems from the exclusive lists below.
Step 3 — Difficulty tuning: Google skews harder in our data. Budget extra time for Hard problems if you are targeting that company.
